| Abstract: |
The nebular analysis package in STSDAS has been substantially enhanced, and now includes several new ions and diagnostics, as well as updated atomic data for all supported ions. In addition, new tasks are being added to compute, from ratios of recombination lines, certain nebular physical parameters and the abundances of He$^+$ and He$^{+2}$ relative to H$^+$. |
